or by telephone at: 416 340 9290 ext. 225. Or you can fill out our contact form [here].

Q:

Is GestTrack dependent on any operating system?

A:

A Windows XP-based system is used for GestTrack™ camera analysis, however, cursor control signals can be delivered in many formats to other computers (serial port or tcp, for example). GestTrack™ can therefore control application content on MacIntosh, Linux or Unix operating systems.


Q:

Does GestTrack need a browser like Microsoft Internet Explorer or Netscape Navigator?

A:

GestTrack™ can control virtually any multimedia or internet content. While no browser is needed, content running under any browser can still be controlled.


Q:

How can GestTrack be installed on a system which runs under a public browser interface?

A:

We generally customize our applications and remove browser menu bars. While we can provide controls, regular browsers often have pull-down menus that require fine resolution. As a result, we recommend well-defined icons and large buttons of at least 1” x 1”, or larger, depending on the size of the display. We also suggest limiting access to menu items in order to ensure that the user remains within their desired content.


Q:

When several people are standing in front of the video cameras, which person will GestTrack focus on?

A:

As with a touchpad application, two inputs results in an average.  We generally design systems so that the ‘control point’ fits just one person.  That way, only one person can gesture towards a screen or window, or point within a tracking frame.  If two people do use the system at the same time, the system will generally ignore two inputs and wait until there is one. For clients who want multi-user or multi-touch interactivity, GestureTek offers an Illuminate (non-GestTrack) technology solution.


Q:

Must a user stand at a specific point or place in front of the display screen?

A:

The flexible GestTrack system can provide users with ‘point and control’ capability regardless of their distance from the display screen.  Once the ideal location for user interaction has been determined, the camera is aimed at that specific point or place.  Users experience the best reliability when they stand at this pre-determined point before interacting with the display.


Q:

What are acceptable locations to set up GestTrack?

A:

GestTrack can be set up at any distance from the display screen, as long as the projected image is fully visible to the tracking unit.  High contrast projection is required during calibration.   The degree of direct sunlight and ambient lighting may influence location selection.  The system works best in indoor locations.   Image size is restricted by projection film size.


Q:

What are the key considerations in selecting a location/position for a GestTrack Through Window system?

A: Location considerations: high visibility, high foot traffic to maximize return on investment; positioning in a way that minimizes blockage of through traffic when the display is in use; city zoning bylaws pertaining to the use of video cameras that monitor pedestrian traffic; restrictions on distance of electric signs from the inside of a store window; internet access if required; proximity to electrical outlets, presence of a secure location to house the computer.  We can work around many issues as long as we know about them in advance. 

Q:

How do users gesture with their finger to successfully perform a button click on a presentation?

A:

There are two methods of "clicking" the button. The most accurate and reliable method is for the user to point and hover their finger once they have made their menu selection.  When the user holds the cursor over their chosen button for a pre-determined amount of time, the gesture is recognized by the system as a “click”.  An alternative, less reliable method, is for the user to point and "jab" at a menu item.  If the buttons are large, this gesture will work.  However, with the point and jab method, the user risks moving the focus of the finger and unintentionally selecting the wrong button.


Q:

Are there special gestures to be learned by the user, or are the gestures more intuitive?

A:

The basic system uses "point and hover". A user selects an icon by pointing at it.  This causes the cursor to appear over the icon.  By holding the finger for a set amount of time (generally about 1.2 seconds), the menu item is selected.  It is often useful to post simple instructions by the display, or create a simple video for the screen which invites people to seek information and shows them how to point and control the display. Note that it is possible to program the GestTrack system to recognize special gestures like sweeping your hand from left to right, however, these specialized control gestures are better suited to unique business and industrial applications where users can receive special instructions.


Q:

How does GestTrack use video cameras to replace the touch screen?

A: Two cameras are mounted overhead, looking down at the user's hand. A thin solid-color frame (either black or white) is applied around the "pointing area” to function as a “camera frame”.  The “camera frame” can be applied to the bottom of a kiosk or store window, or can be fabricated as a freestanding unit that users stand at and point through.

Q:

What is the purpose of having a solid color border?

A:

The border assures that people, hands and other motions outside of the screen area do not interfere with detecting and tracking the user’s hand.  Only hands within the border are tracked.


Q:

How does the system work on store windows, where a retailer wants customers to be able to browse through their store window and control an interactive information display?

A:

GestTrack™ cameras can be mounted inside a store within a mall, to look out through the glass of the store window.  Mall customers can point towards the display screen right through the window.  Some retailers like to set up special outside viewing areas that includes audio, but it is not necessary.  Note, different GestureTek technologies other than GestTrack can be used on outdoor retail windows to deliver motion-controlled content such as interactive ads or interactive games.


Q:

Does the GestTrack system need its own computer or can it run on my existing computer?

A: It is generally best if GestTrack runs on its own computer. We can supply an Intel Core2Quad computer that captures gestures and outputs mouse control signals.  The computer uses about 10% of its resources to produce mouse emulation with 30 frame-per-second results. For systems requiring Z access (depth) information we can use up to 30% of the system resources. The remainder of the computer's resources is available for content display. If a client wishes to use their own computer, each case must be addressed individually with GestureTek’s technical support resources.

Q:

What is the process for using my own computer instead of one provided by GestureTek to run GestTrack applications?

A: Your PC must be certified for use with GestureTek products.  We can provide you with the specifications relating to the components that are already tested as certified to work with GestureTek software.  From these specifications, you can make your manufacturer/model selections.  You will send your hardware to us for rigorous testing before approving it as a certified system.  The turnaround on this process is roughly two weeks from the time we receive your system.  You will be invoiced for the testing period based on resources used.  Generally there are 2 to 3 days worth of technical hours used for research and development, installation, troubleshooting, benchmarking and stability testing. 

Q:

How seamlessly can GestTrack be implemented into multimedia applications?

A:

The software is seamless in that we will send standard mouse signals (X,Y and Click) directly from our tracking computer to your computer. We can also provide Z axis if your application is designed to use it).


Q:

What is the accuracy of the GestTrack system? 

A:

 A typical GestTrack system detects over 300,000 effective positions. This is approximately the same number of pixels as in a 640(h) x 480(v) resolution image.  GestTrack’s precision is greater near the center of the screen than near the edges of the screen, therefore the effective resolution is greater than 640x480 near the center of the screen, but less than 640x480 near the edges. The exact distribution depends on the length of the lens and the distance from the camera to the tracking region. GestTrack includes software sub-pixel resolution enhancement, which estimates a higher resolution position so that the cursor appears to move smoothly when a user drags a finger or hand across the screen. This gives the illusion that the system is tracking at the full display resolution even when the display has a significantly higher resolution than the camera.


Q:

I want to add the portable AirPoint hand tracking system to our conference room or boardroom, how will it interface to my in-house computer? How will it interface to a guest's laptop? How does it work with PowerPoint?

A: AirPoint can be challenging to install on your own computer.  To optimize the ‘plug and play’ benefit of the system, we generally provide both the AirPoint unit and a pre-configured shuttle computer. 

Q:

I can’t get the system to work.  What should I do before I call GestureTek Technical Support for troubleshooting assistance?

A: If the display doesn’t power up, check that there is power going into the display, check for loose cables and check that PC input has been performed correctly. Once the display powers up, and the connections on the back of the GestureTek computers are checked, do a restart on the computer.  If difficulty persists, call Technical Support.

Q:

When I launch my content application, I get a blue background with the word “Dazzler”.  What should I do?

A: First, check that your tracker is running.  If the tracker is running, and you still get the above result copy your entire Logs directory from your C:\GestureTek\[GestTrack] directory to your desktop, zip this directory and email it to support@gesturetek.com; Additionally, if you have custom-made content, try to run the default set of effects from the \\Resources\Demos directory (either Classic or Platinum).
